Returns all the different types ofUFoliageTypeassets that a particularAInstancedFoliageActoruses. This function exists because we want to retrieve all instances of all foliage types on an actor, but we can't return nested containers from UFUNCTIONs, so users of this API should call this, and then GetInstanceTransforms.
